Abstract
Abstract An information recording camera may comprise a position determining device for determining the position of a main object in a photographing image field, and a recording device for recording information regarding the position of the main object determined by the position determining device onto a recording medium. A device for calculating a color temperature of a flash light source based on the color temperature of natural light may be provided, and the calculated color temperature may be recorded to facilitate subsequent photograph printing by a lab.
